Hi Folks According to the 8.3 docs I should be able to write: select * from tblretrain where 'ms-ap-t2-02c9' NOT IN (owners); where owners is an array per the following definition CREATE TABLE tblretrain ( pkretrainid integer NOT NULL, mailid integer NOT NULL, train_to smallint NOT NULL, owners character varying(1024)[], bayes_trained boolean DEFAULT false, contents text NOT NULL, CONSTRAINT tblretrain_pk PRIMARY KEY (pkretrainid) ) The problem is that it generates an error: ERROR: array value must start with "{" or dimension information ********** Error ********** ERROR: array value must start with "{" or dimension information SQL state: 22P02 It seems as though postgres is not recognising owners as an array. Any suggestions please ? regards Grant |
